VACUUM' DUST-REMOVER.

Specification of Letters Patent.

Application led December 31, 1908. Serial No. 470,262.

' the removin .of dust from carpets, and other articles, by t e processof air suction through the article being cleaned; and my invention y hasfor its object to provide the receptacle,

. drum-like body, made vofpo'rous material fibers of the c dustl awayfrom closer contact wuth the orreceiver, into which the dust is drawn bysuction, with a filter which will operate like a lsieve to retain thedust in the receiver, and possess, furthermore, the fproperty of4keeping the porous surfaces o thesieve or filter continuously open, forthe assage of air drawnithrough the receiver y the suction mechanism.

-' 'I attain my object by providing, wlthin the receiver, Ia filtercomprising a hollow or and having afleecy surface, such as `cantonviannel, for example,- and I turn the fleecy The-fleecy surface servesto intercept the* articles of dust; the minute eec'e holding theparticles of porous bod of the filter,y and thus maintaininga c earassage for the air drawn throu h the bo y ofthe filter. The. dust partices will cling to the exterior fleecy surface of the filter-body untilthe gravity of the collected .clusters of dust causes the same to dro tothe bottom of the receiver; for the entlre interior of the receiver isplaced in a state of vacuum by the air suction device, and in conseuence the clustering dust is readily precipitated.

The details of my invention are illustrated in the accompanyingdrawings, in which:

Figure 1 is a perspective view of a portable vacuum dust iremover, orcarpet cleaner machine, embodying my invention, whichis disclosed in thebroken-away receiver; and Fi 2 is a vertical section of the receiver anthe filter therein contained.A Fig. 3 is Jn enlarged detail view of apiece of the fabric from which the body ofthe dust filter cant takenfrom the operating parts.

The letters ydesignate Vthe arts described. a represents a truck, on wich is mounted a dust-receiver, b, within which is contained my filter,c, which is suspended by its upper end from the pi e, d, extendin headcof the Iter, throught e wall of the receiver, b, to the rotary air-pumpe' the latter being driven by a motor f, an oplerating connections. g isa muiler into w ich the air, sucked throu h the receiver, is, in the`first instance, disc arged, so as t0 avoid the annoyance of sprayinglubricant, Iwith such discharge; since 'the dischar ed air would be moreor less laden with lulri- A more com rehensive 'deta of. theyarrangement of t e receiver and filter, `above referred to, is shown inthe enlarged sectional view of the parts in Fig. 2. lThe rece'iver, b,is made with a removable head b". Near the base of the receiver isprovided. an inlet nipple h, to which is connected the piece. Thesuction pipe, d, enters `throu h the wall of the receiver, near the top.T e inner end of said pipe, d, extending through the top end-piece c ofthe filter c, and serving as a support for the latter..l Thebody of thefilter, c, is made of. some porous material, which possesses theproperty of excluding dust, and at the same tlmeprevents clogging of'the pores, so as not to interfere with the free passage of-air suckedthrough the receiver by the rotary `air` um. `e.

In my experiments, I have dlscovered that canton fiannel is admirablyadapted for the service required. The fleecy surrfaceof-canton iiannelbeing 'turned out, and besides Aproviding a fine sieve, vthe minutefibers thereof a" serve to hold the particles of dust away from closercontact with thev porous' body of the filter, and by vso doing insuringa free passage for they air drawn through the 1004 body of the filter.

The body of the filter is a sack-like structure,o en at both ends, whichAends are removab y fastened to the top and bottom endpieces c', c. Eachof said end-pieces is pro- 105 .vided with,l a `flange c', adaptedtohavethe o en ends of. the receiver body fastened l t ereonl by meansof a cord wound around the end of the sack on such flange. The bot- -tomend-piece c? has no opening. The fil- 110 from the l I .wise in keepingthe hollow filter-body expanded. Such effect may be' conveniently-accomplished by weighting the bottom cnd-l piece 02, or by choosingmaterial for making thesame of sufiicient weight.

I claim: Y l. In a vacuum dust remover, the combination of a receiver, adust filter within the receiver, said filter comprising a hollow bodyformed of fabric with the fibers thereof extending from the outersurface, a suctionV pipe communicating with the upper end of the dustfilter, said pipe also forming a support for the dust receiver, an inletpipe communicating with the receiver at a point below the dust filter,the suction of the air through` the dust filter causing the latter to bevibrated to shake the accumulated dust from the fibers.

2. In a Vacuum dust remover, the combination of a dust receiver providedwith an inlet orifice, a dust lter within and spaced from the innerwallsof the dust receiver, said filtercomprising a hollow body of fabricprovided with fibers extending outward y therefrom into the space formedbetween the filter and receiver, a suction conduit. extending throughthe wall of the dust receiver and into the dust filter the suction inthe conduit drawing the dust from the inlet orifice toward and intocontact with the extended fibers and as the latter is vibrated by theaction of the air current the accumulated dust falls into thereceptacle.

3. In a vacuum dust remover, the combination of a dust receiver providedwith an inlet orifice, a dustfilter sus ended within the receiver, saidfilter comprising a hollow body of fabric having outwardly extendedfibers, the lter being spaced from the walls of the receiver to providea space entirely around said filter, a suction conduit extending intothe filter,y the inlet orifice being below the bottom ofthe filterwhereby the suction of air in the conduit will draw `the dust laden airin the space against the extended bers and the Vibration of thelter bythe action of said air will shake the accumulated dust from the fibers.

4. In a vacuum dust remover, vthe .nation of a receiver provided with aninlet orifice, a Idust filter within and spaced from combithe walls ofthe receiver andconsisting of Vinlet orifice being below the bottom ofthe filter.

5. In a vacuum dust remover, the combination of a receiver provided withan inlet orifice, a dust filter within the receiver and spaced from thewalls thereof, said filter comprising a hollow body made of fabrichaving outwardly extended fibers, end heads having flanges over whichthe ends of the fabric 4body are secured, and a suction conduitextending through the wall of the receiver and the upper head of thefilter to cause the dust ladened air to contact with the extendedfibers.

6. In a'vacuum dust remover, the combination with a receptacle having aninlet' orifice a lterin the receptacle, said filter consisting of avbodyof fabric having fibers ex-y tendin therefrom and a suction pipe arrangeto communicate with the interior of the vfilter to draw the dust ladenair from the inlet orifice into directoontact with the ex-l tendedfibers.
